Title: Device for producing electrolytic ion water
Inventor: KATAKABE ICHIRO
IPC: C02F1/46
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To enable an electrolytic ion water producing device to highly efficiently produce high purity electrolytic ion water suitable to be used for the manufacture of a semiconductor device. SOLUTION: For example, NH4 F is added to H2 O to prepare mixture liquid and the mixture liquid is supplied to fill electrolytic cells 11a, 11b. Then an electric current is applied on electrodes 13, 14. During acid and alkali electrolytic ion water is produced by this method, a SiO2 film growing on the surface of the electrode 13 is removed by HF2 <-> which is produced from NH4 F and H2 O. Thereby, even when C or SiC is used as an electrode material, growth of a SiO2 film on the surface of the electrode 13 can be prevented and an electric current can be applied for a long time.

Abstract: PROBLEM TO BE SOLVED: To reduce an adverse effect of an external noise on magnetic recording by forming a spool chamber of a magnetic member and imparting a magnetism shielding effect to the spool chamber. SOLUTION: The spool 3 itself is formed of a magnetic body in order to shield a magnetic flux generated by a motor 2, and at one end of the cylindrical body, a flange for controlling the position of spool rubber 4 is formed, and at the other end, a pawl part for transmitting the rotation of a spool gear 5 to the spool 3 is formed. The spool rubber 4 is stuck on the outer periphery of the spool 3 so as to be formed into one body, and a film pressed by rollers 8 and 9 against the spool rubber 4 is wound up by the friction of the rubber. At a U-shaped part for storing the spool in the spool chamber 1e, a magnetic material layer is formed by sticking the magnetic material to the inside wall.  In order to prevent the adverse effect of the magnetic flux of the motor which is still more leaked from the spool 3 formed of the magnetic material from being given to a magnetic head, the magnetic flux is guided by the magnetic material layer in a direction opposite to the magnetic head.

Filed: 1989-09-28
Abstract: PURPOSE:To protect other circuit elements against breakdown by arranging a circuit element for limiting overcurrent between a saturable reactor, which controls the gate of an element for switching a DC power supply alternately and performs commutation, and an auxiliary winding. CONSTITUTION:Upon start of a self-exciting converter 1, an N-type MOSFET 5A is turned ON while a P-type MOSFET 5B is turned OFF. Under this condition, a constant exciting current flows from an auxiliary winding 19 through a constant current diode 51 in a current limiting circuit 50A to a saturable reactor 7 thus sustaining excitation. The reactor 7 is short-circuited upon saturation and the FET 5A is turned OFF thus charging a capacitor 27 with the inductive energy in a main transformer T. Subsequently, the FET 5B is turned ON and a current starts to flow through the reactor 7 in reverse direction. Excessive current starts to flow through the auxiliary winding due to short circuit of the saturable reactor 7, but it is limited by constant current diodes 51, 52.

Abstract: PROBLEM TO BE SOLVED: To suppress the heat generation of the polarizing plate on the incident side of a liquid crystal display element as far as possible and to obviate the occurrence of the deterioration and dimensional change of the materials of the liquid crystal display element, hologram layer, etc., by using two sheets of the polarizing plates on the incident side of the light for illumination of the liquid crystal display element and subjecting the light scattered slightly in the polarization state after the passage through the hologram layer to correction of the polarized light with the polarizing plate of the second sheet. SOLUTION: The polarizing plates 12, 14 on the incident side of the light for illumination of the liquid crystal display element 6 are formed of two sheets. The polarizing plate 12 is arranged nearer the light source side than the hologram layer and the polarizing plate 14 is arranged between the hologram layer and the liquid crystal display element 6. The polarized light is aligned by the first sheet sheet of the polarizing plat 12 nearer the light source side than the hologram layer and the light scattered slightly in the polarization state after the passage through the hologram layer is subjected to the correction of the polarized light by the second sheet of the polarizing plate 14 arranged between the hologram layer and the liquid crystal display element 6.  In such a case, the incident light on the second sheet of the polarizing plate 14 is aligned mostly in the plane of the polarization and, therefore, the absorption of the light for correcting the plane of polarization is very small and there is substantially no heat generation. The adverse influence on the other elements is thus prevented.
